u represents tite pilot-beam or end s ill oi' a locomotive 4engine or tender, which isotonposed preferably of east. steel integral throughout and in the .present ease; bojxshaped in cross seetion having a forware and downward exitension at. its middle portilpn 'as shown. i l

portion between the respective walls thereof,

is formed a receptacle or housing b for the springs and adjacent combined parts of the draft-gear, the housing l; having` an opening 1 .therefrom through its front .wall 2 and 60 front side oli the beanr o thereat, adapted tor the free passage therethrough and play ot the coupler-shank or dra \vbar c as hereinafter more particularly referred to.

A. Through the bottom wall 4. of the housing l 7) 1s'for1ned an opening 5 for the insertion therethrough ot a cross-head (Z which is arranged horizontally withinvthe housing b at right angles toand in the plane of the drawhar e. the' cross-head fvhaviug in its front 730 side` opposite and eorresponding to the front opening l ot the housingr o, a ret:tangular-1 shaped recess t of suitable depth, containing :ue'entral pocket. which adapted to 'reil' cei\"e. and having a. top depending. and botl tom upwardly projecting lug '8, and 8', re-

, spectivcly, adapted to hold, the rear vend pori tient) of the draw-bar c, in the assembled or 5' Y.service position of the parts, one Slde of the L pocket 7 being closed and its other side open ist) and spaced apartvfroin the correspondingend of the recess sufficiently to4 permit initially of the insertion within that part of the recess 6', ot' the rear end portion 9, when entered and passed with the draw-bar c parallelly to .the longitudinal center of the engine frame through the front opening'l, the', draw-bar c being' then moved transverselyj along the opening' l 4and its rear end portion 9 passed laterally into the pocket 7 between 90 the rear wall-atil'ihe front lugs S,4 S', thereof, in vwhich position it is secured to the crosshead (l by bolts 10 in the usual manner. Between. and eudwise against the crosshead (l and the front wall .Zof the housing ateaeh side of the recess t3 and the said center, are arranged the. draft springs c which bear on the bottom wall 4 ofthe lionsin; while between and endwise against the eross-head J and the rear wall ll of the 133 housing l', in alim-*ment with the draft7 springs e aiearr'angedthe btttii1'ig.spriiigs c. the springs c, and c', being operated by the cross-.head l outhe pulling and bniiing movements respectivelyofthe draw-bar e Awithout. the use of follower-plates, thereby .enabling the parts to oceupyless space and with less forward projection of the middle portion of the beam u.- and coupler than 1n t 55 ln the pilot-beam u at. its middle extetnded' the ordinary pilot-beam draft-gear; also by '110 i l l I l i t lt' l s i .a .i i i f, i i f -i It t i l; ,s i f 'l l t Q eo4,221

making the opening 1 in the front Wall 2 abnormally Wide for permitting the initial passage therethrough of the draw-barv c parallelly .to the longitudinal center of the engine frame, the adjustment and connec tion of its rear end portion 9 to the crosshead ci isreadily effected Without the necessity of forming clearance-ways therefor in the top or bottom member of the beam which weakens the casting at the part-whereits maximum Vstrength is required.

For reducing the abnormal width of the opening 1 through the front Wall 2 of the housing b and lnniting the lateral play of the draw-bar c therein from its normal central or service position, I intel-pose between the draw-bar c angl the bottom of the, opening 1, a carrier-plate f which extendsl rearward for a suitable distance within the housing t), and on which the draw-bar c rides at all times, the plate f having two opposite upright lateral flanges' 12 which are adapted to reduce the spaces between .the draw-bar c and the sides of the openinr 1 and 'extend' .rearward therefrom along the-plate j parallel and in proximity to the draft s )rings c which are thereby held laterally in p ace.

l/Vhat I- claim as my invention and desire to secure by Letters Patent is l. ln `draft-gear for a locomotive engine or tender, the combination withV the end-sill of the frame, of'adraw-bar having a suitable 'head and coupler, a housing formed in andhavmg-an opening through the front side of the said sill adapted for the assage therethrough and play of the drawar, a draft spring and a bufhng spring ahned to each other on each side Iof the longitudinal cen` iter of the saidframe within the housing,

andada t'ed to bear at their outer ends respeetive y, against the front and rear Walls thereof, a cross-l1ead-intermediate to and adlapted to bear against 'the inner ends of the said springs, and having a recess in its front side opposite'to the said opening for receiving the rear end portion of the drawbar on its initial passage longitudinally through thel said opening, a pocket in the recess adapted .tol receive and hold the said portion in its ultimate normal central position, means for assembling the springs and cross-head Within the housing, and for {ixing the drawbar to the cross-head, substantially as described.

2. In draft gear for a locomotive engine or tender, the combination with the end sill of the frame, of a draw-bar having a suitable headand coupler, a housing formedin' and having an opening through 'the front side o f the said sill adapted for the passage therethrough und play of the draw-bar, a

draft spring and a butling 'spring Y uhned to each other on each side of thelongitudinal center of the said frame within .the housing, and adapted to bear at their outer ends respectively, against the front and rear walls' thereof, a; cross-head intermediate to and adapted to bear against the inner ends of the sald springs, and having a recess in its front side opposite to 4the said opening for receiving the rear end portion ofthe drawbar on its initial passage longitudinally through the said opening, a pocket in the recess adapted to receive and hold the said portion in its ultimate normal central position, means for"limiting the play of the draw-bar from its said position toward the sides of the said opening, and for preventing lateral displacement of the draft springs within the housing, substantially as described. i
